hexadecane: Reaction mechanisms," Industrial and Engineering Chemistry Fundamentals, vol.
To these aims, previous experiments with non-ionic surfactants (Cruz, 2012) and
hexadecane (Garcia-Valero, 2011) showed that mixtures of dodecane with at least 7% wt/wt of squalene (SQ), or 30% wt/wt of tetrachloroethylene (TCE), respectively, were required.

hexadecane, and squalane with benzene at 298.15 K," Journal of Chemical and Engineering Data, vol.
The glass membrane (Shirasu porous Glass, SPG) emulsification technique was employed and styrene as a monomer mixed with water-insoluble
hexadecane (HD) was used for investigation.
Common secondary metabolites present in leaf tissue and leaf calluses were toluene, a-sphinosterol, quercetin, tetradecane, pentadecane,
hexadecane, octadecane, hentriactone and 9,12-octadecadienoicacid[7,7] (Table II).
Among secondary metabolites determined, the common secondary metabolites present in leaf and internode tissues were Toluene, a-sphinosterol, Tetradecane, Pentadecane,
Hexadecane, Octadecane, Hentriactone, and 9,12-Octadecadienoicacid[7,7].
Water (hydrophilic and capable of forming hydrogen bond with the substrate) and
hexadecane (nonpolar, oleophilic liquid) were used as test liquids.

Cetane number refers to a similar property for diesel fuel, for which normal
hexadecane ([C.sub.16][H.sub.34]) is the standard molecule.
The ability of wax-degrading isolates to grow and produce biosurfactants on hydrocarbon was assessed by measuring changes in the surface tension of growth medium containing
hexadecane as a sole carbon source.
